Development in the first four months after birth is rapid and can be surprising. As babies connect and communicate with their carers, and develop eating and sleeping patterns, they learn through sensory experiences.

The Australian Government's Early Years Learning Framework Practice Based Resources - Developmental Milestones provides guidance through a range of milestones that fall into the categories of physical, social, emotional and cognitive. 

However babies all develop differently and each child is unique. The milestones should be considered guidelines, and parents shouldn't be concerned unless their child displays one of the criteria under which it is recommended that they seek advice. 

Goodstart Early Learning Queensland Regional Manager Deon Hemberg says it’s important to make the most of moments that matter through quality interactions. 

“We need to nurture young infants with gentle voices. Stroking and caresses, welcoming facial expression and eye contact regulate an infant’s capacity for arousal and recovery,” Deon says.

“Gradually young children’s capability for self-regulation grows from this early foundation. Establishing these rich nurturing relationships and welcoming environments will encourage regulation and well-being.”
